How I began my journey with Golang on a Raspberry Pi and had my first real world application working within the afternoon: a client for my connected display server. Follow me step by step along the way (code included)

Hi,
No prior Go experience, although I know several langages.
I had to search for the difference between = and := operators, but apart from this, it was just a matter of tweaking existing code and learning along the way.

The Blinkt! is not mandatory, but it sure is fun, and comes with a Go lib, so that was the perfect pretext :) Learning by playing works well for me.

Thanks,
And no offense taken: you're right.
I got a good first feeling with Go and will now read some background doc and good practices.
This was just a quick copy/paste/edit job to see if all played well together, I can only guess how awfull it must look to a real Go coder :D
